Only content/ now has the ability to create BrowserThread objects, with the exception that tests can create the content::TestBrowserThread subclass, and (temporarily) code in chrome/ can create the DeprecatedBrowserThread subclass. A follow-up change will make content/ take care of its own thread creation, remove DeprecatedBrowserThread, and move all state and non-trivial constructors from BrowserThread down to BrowserThreadImpl. Also moved BrowserProcessSubThread into content/ namespace. As part of follow-up cleanup, chrome/ will stop using this class.
